When Empty, the Clip is supposed to Immediately Fall Down and Out of the rifle magazine. The Clip Not being visible dangling from the magazine means: (1) It is Loose/Free inside the weapon, or (2) Completely Absent/Missing from the weapon.
The BRASS clip does NOT rattle around in the magazine ...Brass is non ferrous and can be compared to copper ...it simply doesn't clink or rattle like a ferrous metal...
I just placed an empty brass clip in a carcano and I shook it, in an effort to make the clip rattle... It did not...Hoever something interesting happened...The clip slipped down to the exact point that the clip is seen in Alyea's film,... which is about 1/8 of an inch of the clip visible in the magazine....
Believe it or not....
